Embodiment Construction
[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0020] see figure 1 , The tail drive shaft support device of the present invention includes: a support seat 1 , a bearing seat 3 and a bearing 5 . Wherein, the bearing seat 3 is fixedly installed on the support seat 1 , and the bearing 5 is fixedly installed on the bearing seat 3 .
[0021] The support base 1 includes a fixed base plate 11 , on which a first fixed plate 13 and a second fixed plate 15 perpendicular to the fixed base plate 11 are disposed. The first fixing plate 13 and the second fixing plate 15 are disposed on two sides of the fixing bottom plate 11 opposite to each other. A mounting groove 17 is formed between the first fixing plate 13 and the second fixing plate 15 . A plurality of fixing holes 19 are also provided on the fixing...

The invention provides a tail driving shaft support device. The device comprises a supporting base, a bearing base and a bearing, wherein the bearing base is provided with a plurality of joint bearings, the bearing base is fixedly mounted on the supporting base through the joint bearings, and the bearing is fixedly mounted on the bearing base. With the adoption of the tail driving shaft support device, the technical problems that the existing support device cannot withstand angular deviation generated when a tail driving shaft is mounted, and vibration and displacement generated when the tail driving shaft works, and further, cannot be applicable to the tail driving shaft with a supercritical design are solved, and then, effects that the influence on the tail driving shaft caused by the vibration of the fuselage of an airplane can be effectively isolated, and further, the angular deviation generated when the tail driving shaft is mounted, and the axial displacement and the circumferential displacement generated when the tail driving shaft is supercritical can be withstood are reached.
Description
technical field [0001] The invention relates to the field of mechanical transmission, in particular to a tail drive shaft support device of a helicopter. Background technique [0002] In the tail drive shaft assembly of the helicopter transmission system, there are many structural forms of the tail drive shaft support device. At present, rubber or rubber sleeves with silicone oil are generally used to wrap and fix the stern shaft ball bearings. This structural form can only provide support for the tail drive shaft, and can withstand the vibration generated when the tail drive shaft works. However, this structural form cannot bear the angular deviation caused by the installation of the tail drive shaft and the displacement during operation, and it cannot be suitable for the supporting device of the tail drive shaft with supercritical design. Contents of the invention [0003] The purpose of the present invention is to provide a tail drive shaft support device to solve the...
